AI Technical Summary

Benefits of technology

The invention is a clamp with a cam that can be easily removed and refitted by the user without any risk of error or damage. This makes it easier for users to replace the clamp without needing to replace the entire device.

Problems solved by technology

The fitting and removal operations of these flexible biasing means are not easy for the user to perform with a clamp with a removable pin.
Refitting of these springs is not easy when the cam and pivot-pin assembly is fitted in the trough.

Embodiment Construction

[0021]With reference to FIGS. 1 to 7, a clamp 10 is designed for secured progression of a climber on a fixed rope, and for forming reeving or hoisting systems.

[0022]The clamp 10 comprises a U-shaped metal body 11 provided with a central trough 12 for passage of the rope, and an actuating lever 13 with blocking cam 14.

[0023]The actuating lever 13 can swivel around a transverse pivot-pin 15 between a first jamming position and a second unblocking position of the rope. The cam 14 extends at the inner end of the actuating lever 13 facing the bottom of the trough 12 so as to block the rope against the bottom of the trough 12 in the first position. At the opposite end of the cam 14, the actuating lever 13 is provided with a circular aperture 16 accessible from the outside of the trough 12 for attaching a safety means (not shown) designed to be connected to the climber's harness.

[0024]The safety means can be a carabiner, a cord or a strap. The surface of the cam 14 coming into contact with...

Abstract

The invention relates to a clamp with a cam, and with a removable pivot-pin, wherein the bias spring is integrated in a housing of the cam by means of a securing cassette configured to position the spring in a pre-stressed state. The cassette is provided with clip-fastening means designed to be fitted in the housing of the lever.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to a clamp on a rope comprising:[0002]a U-shaped body equipped with a trough for passage of the rope,[0003]an actuating lever having an aperture for attaching a safety means, and a cam for jamming the rope, said lever being housed in the trough by means of a removable pin,[0004]and a bias spring biasing the cam towards the rope.STATE OF THE ART[0005]Known clamps of the kind mentioned comprise a U-shaped flange forming a trough, a lever with a blocking cam, and a removable pin enabling the clamp to be fitted or removed at any point of the rope. The lever and the detached pin remain joined to the body of the clamp by a flexible link to render them captive after the pin has been removed. Return of the cam in the direction of the rope is performed by flexible biasing means, for example by flexion of a cable, or by the action of a torsion or traction spring. The fitting and removal operations of these flexible biasing means are not e...
